DEVICE FOR-SECURING DIALS TO WATCHES.

SPECIFICATION forming part of Letters Patent No. 419,525, dated January14, 1890.

Application filed July 12, 1889. Serial No. 317,259. (No model.)

To all whom it may concern;

Be it known that I, FERDINAND F. IDE, a citizen of the United States,and a resident of Peoria, in the county of Peoria and State of Illinois,have invented certain new and useful Improvements in Devices forSecuring Dials to Watch-Plates; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and is aview of the under side of the dial. Fig. 2 is a top View of thewatch-plate. Fig. 3 is an edge view of the plate and dial. Figs. 4, 5,6, and 7 are details.

This invention has relation to means for securing dials to watch-plates;and it consists in the novel construction and combination of parts, ashereinafter set forth.

In the accompanying drawings, the letter A designates the watch-plate,to which the dial B is attached. This plate is provided with theapertures C, which receive the feet D of the watch-dial, said feet beingmetallic studs, which are divided or split endwise, the cleft beingradial with relation to the center of the dial-plate. Communicating witheach aperture C is a threaded perforation E, which extends inward fromthe edge of the plate radially, as shown, its direction being at rightangles to the axis of the aperture 0.

F is a small screw, which is designed to enter the perforation E andengage its thread. This screw has a conical pointed end G, which, whensaid screw is driven home, is designed to enter the cleft of the foot ofthe dial-plate and to spread the branches II II thereof to cause thelatter to engage the wall of the aperture 0. In this manner the dial isfirmly and securely fastened to the watch-plate without using force orupsetting the stud, and the dial can be removed when necessary andreplaced with the greatest facility.

Having described this invention, what I claim, and desire to secure byLetters Patent,

1. The dial having the radially-cleft feet adapted to be spread in theirseats in the watch-plate to fasten the same thereto, substantially asspecified.

2. The combination, with the watch-plate having threaded perforationscommunicating at right angles with the apertures O, of the dial havingradially-cleft feet and the pointed fastening-screws, substantially asspecified.

In testimony whereof I affix my signature in presence of two witnesses.

FERDINAND F. IDE.
